QUIZ 1. What does the Baltimore classification relies on to make the differentiation between different types of viruses? a. The virus particle’s basic structure b. The type of nucleic acids in the genome c. The length of the viral particle’s genome d. The protein coat on the outside of the particle Answer: b. The Baltimore classification is based on the type of nucleic acids in the virus particle’s genome. 2. What is the protein coat around the individual virus called? a. Viral particle b. Virion c. Envelope d. Capsid Answer: d. The capsid, which is the protein coat that surrounds the viral nucleic acid molecule in order to protect it, is seen on all viruses. 3. What viral hypothesis on the origin of these entities indicates that viral particles developed and evolved billions of years ago at the origin of life itself? a. Vagrancy hypothesis b. Regression hypothesis c. Escape hypothesis d. Virus first hypothesis Answer: d. The virus first hypothesis indicates that viruses developed and evolved since the beginning of life on earth and didn’t require cellular structures to help develop the virus particles.
